Abstract
A bump is formed on each element electrode of a semiconductor device, and a thermoplastic resin sheet is aligned in position with the semiconductor device. The sheet and the semiconductor device are subjected to hot pressing to melt the sheet, forming a thermoplastic resin portion that covers a portion other than the end surface of each bump of the semiconductor device. The thermoplastic resin portion obtained after the hot pressing is cut.
